Well, my dad picked up his volt last weekend. Very impressive car to say
the least, I drove it in electric mode and had it up to 95mph in full
electric mode in short order. It has the slight "sag" in power at around
60-70, then picks up to 90 as the secondary electric motor kicks in to help.
Impressive.
Anyway, this morning I drove his insight back from my house to his (I
had to drive it home from the dealership) and we took a run from his
house to mine. I've done this run many times with my 1994 US Electricar
Prizm (50kw, 300v pack, 52ah capacity AGM) and it takes a good 23 ah of
current to make the run from his house to mine. He and I both have 6.6kw
Magnechargers, so I can make the trip up, charge for 2 hours, and make
it back.
The Volt's battery capacity is 16kw-hrs raw, 10.4kw hrs usable. So I
will assume that the gauges calculate based on the 10.4kw.
The Prizm has a [email protected] or 15.6kw pack. Usable capacity at 60a
draws (highway speed) is 12.6kw to empty. Using the 20% reserve capacity
rule (discharge to 80%) we get a usable capacity of 10.08kw.
On the drive to the house, the Volt covered the distance using 70% of
it's usable battery capacity. Based on it's pack capacity of 10.4kw
usable that put it at 7.280 kw used.
The Prizm making the same run uses [email protected] (average) to go the exact
same distance. That works out to 6.9kw/hr.
So for a rough estimate, it looks like the Volt uses about as much power
as the Prizm. Given that they are about the same shape and weight (I'm
guessing the motor weighs about 700 pounds plus 300 for the pack would
compare to the 1,100 pounds for the Prizm pack) that once again makes sense.
Unfortunately the Volt does *not* come equipped with a Class II
Magnecharger port, so he could not do a quick recharge at my house. I do
not know why
But he can use the gas engine to get home.
Come springtime we'll have to drag race each other a bit.
